Mixing and tight polyhedra

Thomas Ward

Actions of by automorphisms of compact zero-dimensional groups exhibit a range of mixing behaviour. Schmidt introduced the notion of mixing shapes for these systems,…

Mixing actions of the rationals

Richard Miles, Tom Ward

We study mixing properties of algebraic actions of , showing in particular that prime mixing actions on connected groups are mixing of all orders, as is…

Primitive divisors of elliptic divisibility sequences

Graham Everest, Gerard Mclaren, Tom Ward

Silverman proved the analogue of Zsigmondy's Theorem for elliptic divisibility sequences. For elliptic curves in global minimal form, it seems likely this result is true in a unifo…

Orbit counting with an isometric direction

G. Everest, V. Stangoe, T. Ward

Analogues of the prime number theorem and Merten's theorem are well-known for dynamical systems with hyperbolic behaviour. In this paper a 3-adic extension of the circle doubling m…

Isomorphism rigidity in entropy rank two

Manfred Einsiedler, Thomas Ward

We study the rigidity properties of a class of algebraic Z^3-actions with entropy rank two. For this class, conditions are found which force an invariant measure to be the Haar mea…

Periodic points for good reduction maps on curves

Manfred Einsiedler, Graham Everest, Thomas Ward

The periodic points of a morphism of good reduction for a smooth projective curve with good reduction over the p-adics form a discrete set. This is used to give an interpretation o…
